Propagating user privacy preferences across multiple applications

ABSTRACT

Methods and systems for maintaining user privacy preferences based on one or more user identifications across a plurality of applications are provided. Two or more user identifications are received with associated user privacy preferences. The received user identification is compared against other user identifications to determine if the user identifications relate to the same user. It may be determined that two user identifications are related if they have at least one browser property in common. A consolidated data stream of the user privacy preferences for the related user identifications is created. The consolidated data stream is communicated to one or more applications and propagated to maintain the user privacy preferences across the applications relating to the user identification.

BACKGROUND

Online targeted advertising includes the responsibility of an advertisement network to offer a user a choice to opt out of the targeted advertising. Currently, the opt-out setting is usually implemented using a non-persistent cookie. In other situations, the opt-out state requires a user to log on to another online service. In the situation using a non-persistent cookie, clearing the browser cookies loses the opt-out state and therefore, causing the user to have to choose the opt-out state every time the cookies are cleared. The other situation, involving logging on to an online service, adds another step for the user to maintain the opt-out settings. Opt-out settings may include other online preferences settings such as targeted advertisement settings and pop-up settings but is not limited to only these settings.

In embodiments, the information stored in association with the identification correlation map store 290 is configured to be searchable.

It will be understood and appreciated by those of ordinary skill in the art that the information stored in the application information store 230, and/or the identification correlation map store 290 may be configurable and may include any information relevant to user identifications and associated user privacy preferences, and the like. The content and volume of such information are not intended to limit the scope of embodiments of the present invention in any way. Further, though illustrated as two, independent components, the application information store 230 and the identification correlation map store 290 may, in fact, be a single data store, and/or may have portions which reside on a server (not shown), the personal computing device 210, another external computing device (not shown) and/or any combination thereof.

It should be understood that any number of personal computing devices and data stores (e.g., application information store 230 and identification correlation map store 290) may be employed in the computing system 200 within the scope of embodiments of the present invention. Each may comprise a single device/module or multiple devices/modules cooperating in a distributed environment. Additionally, other components/modules not shown may also be included within the computing system 200.

It should be understood that this and other arrangements described herein are set forth only as examples. Other arrangements and elements (e.g., machines, interfaces, functions, orders, and groupings of functions, etc.) can be used in addition to or instead of those shown, and some elements may be omitted altogether. Further, many of the elements described herein are functional entities that may be implemented as discrete or distributed components or in conjunction with other components/modules, and in any suitable combination and location. Various functions described herein as being performed by one or more entities may be carried out by hardware, firmware, and/or software. For instance, various functions may be carried out by a processor executing instructions stored in memory.

Generally, the computing system 200 illustrates an environment in which maintaining user privacy preferences based on one or more user identifications across a plurality of applications. As will be described in further detail below, embodiments of the present invention propagates a user's privacy preferences across different applications to maintain the settings previously set by the user. Therefore, even if a user clears the browser history or cookies, the privacy preferences will be maintained. Additionally, embodiments of the present invention permit privacy preferences including opt-out settings, targeted ad settings, a pop-up ad preference, the absence of any user privacy preference, and other settings.

With continued reference to FIG. 2, the data processing device 250 may include a receiving component 260, a communication component 270, and an evaluation component 280. The receiving component 260 is capable of receiving one or more user privacy preferences associated with one or more user identifications. The evaluation component 280 is capable of evaluating that one or more user identifications related to the same user using identification correlation from the identification correlation map store 290. The communication component 270 is capable of communicating a consolidated data stream of the one or more user privacy preferences associated with at least one of the user identifications to one or more applications.

The evaluation component 280 is configured to compare the received user identification(s) with the user identification stored in the identification correlation map store 290. Such determination may be made utilizing metadata conveyed, for example, via one or more of a browser property from, for example, the personal computing device 210 such as a user's IP address, a session ID, a cookie associated with the user, and a browser user agent. If the evaluation component 280 determines that two user identifications related to the same user, then the user identifications will be correlated in the identification correlation map store 290 for future reference. The evaluation component 280 may use a cookie graph to determine if the received user identification is related to another user identification.

Determining that one or more user identifications are related based on having a least one browser property in common, the communication component 270 may be configured to create a consolidated data stream of the user privacy preferences associated with the related user identifications. The consolidated data stream, communicated by the communication component 270, may be configured to be received by the application information store 230 to propagate privacy preferences across different applications for a particular user.

Also, it may be determined that the user identifications have conflicting associated user privacy preferences. Upon determining that the associated user privacy preferences are not conflicting, the associated privacy settings will be propagated to the one or more applications. Upon determining that at least two of the associated user privacy preferences are conflicted, the respective user privacy preferences associated with the user identifications having the conflicting settings may be maintained. For instance, the most recently set user privacy preferences might be determined to be the user privacy preference propagated while maintaining the conflicting privacy preference in the only the corresponding application.

Turning now to FIG. 3, a flow diagram is illustrated showing a method 300 for maintaining user privacy preferences based on one or more user identifications across a plurality of applications, in accordance with an embodiment of the present invention. As indicated at block 310, a plurality of user identifications is received. For instance, one of the applications prompts a user to set privacy preferences and the user identification, associated privacy preferences, and browser properties are transmitted by the browser 220 of the personal computing device 210 to the data processing device 250 of FIG. 2. A user might have a different identification for each application.

As indicated at block 320, the plurality of user identifications is compared. For example, if a user has different user identification for each application but uses the browser 220 on the same personal computing device 210 of FIG. 2 to access each of the applications, then at least one of the browser properties associated with the user identification would be the same. The evaluation component 280 of FIG. 2 is configured to compare the user identifications by accessing the identification correlation map store 290 of FIG. 2. The identification correlation map store 290 may contain a database of user identifications with associated privacy preferences and browser properties. The evaluation component 280 correlates the user identifications based on the browser properties. Examples of browser properties include, but are not limited to IP address, browser user agent, a session ID, and a cookie associated with the user. The correlation of the user identifications is used to determine if user identifications relate to the same user.

The evaluation component 280 may use a cookie graph to determine if the received user identification is related to another user identification. Also, the user identifications may be correlated through a common mapped identification. For example, user identification relating to a user A (ID A) is determined to be related to a user identification relating to a user B (ID B) by some common properties, such as browser properties. A user identification relating to a user C (ID C) is determined to be related to ID B also by some common properties. Therefore, it may be determined that ID A and ID C are also correlated. Further, it may be determined that ID A, ID B, IDC all belong to the same user.

Once it is determined that at least two user identifications relate to the same user, a consolidated data stream of the privacy preferences associated with the related user identifications is created, as indicated at block 330. The consolidated data stream is created to easily transmit the related user identification and privacy preferences to multiple applications.

As indicated at block 340, the consolidated data stream is communicated to one or more applications. Once the consolidated data stream is received, the information contained within the data stream (e.g. privacy preferences) is propagated across all relevant applications. For example, once a user chooses to opt out of all targeted ads in a first application and it is determined that the user has a user identification for a second application, then the user will be opted out of targeted ads in the second application, as well as, for the first application.

With reference to FIG. 4, a flow diagram is illustrated showing a method 400 for maintaining user privacy preferences based on one or more user identifications across multiple applications, in accordance with an embodiment of the present invention. As indicated at block 410, a first user identification and associated privacy preferences is received for a first user. For example, a user has indicated a privacy preference in at least one of the applications using browser 220 on the personal computing device 210 of FIG. 2. As indicated at block 420, a second user identification and associated privacy preferences are received. This may happen, for example, when a second user or the same user as in step 420 indicates a privacy preference. It should be appreciated that there are many different possibilities for the situations with different user identifications. For example, the user identifications might relate to the same user, or might be accessed on the same personal computing device 210 of FIG. 2, and the like.

As indicated by block 430, it is determined that the first user identification and the second user identification have at least one browser property in common. The evaluation component 280 of FIG. 2 is configured to compare the user identifications by accessing the identification correlation map store 290 of FIG. 2. The identification correlation map store 290 may contain a database of user identifications with associated privacy preferences and browser properties. The browser properties help to identify and differentiate the user identifications. The evaluation component 280 correlates the user identifications based on the browser properties. The correlation of the user identifications is used to determine if user identifications relate to the same user. Examples of browser properties include, but are not limited to IP address, browser user agent, a session ID, and a cookie associated with the user. The evaluation component 280 may use a cookie graph to determine if the received user identification is related to another user identification.

Once it is determined that at least two user identifications relate to the same user, a consolidated data stream of the privacy preferences associated with the related user identifications is created, as indicated at block 440. The consolidated data stream is created to easily transmit the related user identification and privacy preferences to multiple applications.

As indicated at block 450, the consolidated data stream is communicated to one or more applications. Once the consolidated data stream is received, the information contained within the data stream (e.g. privacy preferences) is propagated across all relevant applications. For example, once a user chooses to opt out of all targeted ads in a first application and it is determined that the user has a user identification for a second application, then the user will be opted out of targeted ads in the second application, as well as, for the first application.

As can be seen, embodiments of the present invention are directed to maintaining privacy preferences based on one or more user identifications across multiple applications. It will be understood by those of ordinary skill in the art that the order of steps shown in the method 300 of FIG. 3 and the method 400 of FIG. 4 are not meant to limit the scope of embodiments of the present invention in any way and, in fact, the steps may occur in a variety of different sequences within embodiments hereof. For instance, the search engine might simultaneously access the event catalog for relevant events, as well as, access the search history store for a user's interest indicators. Any and all such variations, and any combination thereof, are contemplated to be within the scope of embodiments of the present invention.

While embodiments of the invention are susceptible to various modifications and alternative constructions, certain illustrated embodiments thereof are shown in the drawings and have been described above in detail. It should be understood, however, that there is no intention to limit the invention to the specific forms disclosed, but on the contrary, the intention is to cover all modifications, alternative constructions, and equivalents falling within the spirit and scope of the invention.
